Letters Patent No. 96,664, dated November 9, 1869.

LAMP. i I

'Ihe Schedule referred to in these LetterePatent and making part of the same.

I, Newam BENEDICT, of the city of Washington, in theDist-rict of Columbia, have invented certain Improvements in Lamps, of which the following is a specification.

The object of my invention is to provide a lamp, re quiring no chimney, which lamp, with a moderate consumption of kerosene or other oils, shall givea su- .perior light, and not smoke, or allow the escape of unconsnmed vapors.

The improvements herein set forth, in accomplishing this object, also incidentally lessen the chances of explosion.

Figure 1 is a perspective, showing the lamp complete, with my improvements adjusted as when -in use, the wick being omitted, that the parts may he more distinctly seen.

Figure 2 is the sliding clamp a b c, seen at the top in figs. 1 and 3.

Figure 3 is a vertical section of the lamp, through the middle of the width of the wick-tube.

Figure 4 shows the top of the reservoir, with the wick-tube cut away in a plane with the upper surface of the gauge-plate d. I

The ring D is fitted to the wick-tube, so as to slide up and down upon it.

To this ring clamp-jaws a are hinged, their upper slittcd extremities being so bent that they maybe 'brought to meet over the top of the wick-tube, forming a slitted cap thereon, covering thecnd of the wick with narrow strips of metal, and dividing the base of the flame into several small sect-ions.

From near the ends of these strips, which are designed to close entirely over the wick, claws, marked severally with 0, project downward, so as to clamp against the sides of the wick, and, by means of their turned tips, fasten to it.

They are set at the proper points in the clamp 60 b, to allow of their passing just inside the wick-tube, as seen at 1 and 3. Holding to the wick, they raise or lower it, to correspond with the sliding up or down of ring lg.

Thus the wick is adjusted to the requirements of the flame, by moving the ring I), and no incisions ore, holes in the sides of the tubes are required for appli-' anccs to move the wick. The tube near (I g, fig. 3, should be sufficiently enlarged to allow some looseness in the length of the wick, that its temporary adjustmentsto the flame need not disturb the part of it below (I g,

f d is a press-gauge, for regulating the fiow of oil I tln'onghtho wick.

I g is a straight ridge inside the tube, corresponding exactly with the-inner edge of the sliding plate (I, which is moved by screw j; and if made to meet g, would entirely close the passage from the reservoir to the top of the tube. 1

The action, upon the wick, of plate (I, retards the flow of oil upward. and may ,be made to stop it entirely. The requisite pressure forthe proper flow of oil, efiectually cuts oft all communication, by vapors, between the reservoir and the flame.

. The device indicated by the letters a l) 0 so breaks up the ordinarily compact sheet or column of vapor, in side the flame, as to greatly improve its combustion and lessen the smoke, andthe devicc'fd g, in moderating the flow of oil to the flame, co-opcrates with device a b c, to entirely prevent smoke, at the samev time that the wick and the flame are sutliciently high 't'or a superior light. l

I claim, as my invention- 1. The sliding clamp (L I) c, forming, for the wick, '.t slitted cap or covering, attached and operatingiu the manner and for the purposes hereinbetbre set forth.

2. The construction, in the wick-passage, of the press-gauge f (lg, substantially as and for the purpose 'hercinbetbre set t'orth.-
